Mandevilla plant named ‘Inmanredgran’

ABSTRACT

A new and distinct cultivar of  Mandevilla  plant named ‘Inmanredgran’, characterized by its upright and vining plant habit; strong and moderately vigorous growth habit; freely branching habit; glossy dark green-colored leaves; freely flowering habit; and large red-colored flowers that resist fading.

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘INMANREDGRAN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘Inmanredgran’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Johannesburg, South Africa and Heidesheim, Germany. The objective of the breeding program is to create new strong and freely branching Mandevilla plants that flower freely and have large attractive flowers that resist fading.

The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Johannesburg, South Africa in November, 2010 of a proprietary selection of Mandevilla hybrida identified as code number D09-1067-15, not patented, as the female, or seed parent with a proprietary selection of Mandevilla hybrida identified as code number D09-1067-3, not patented, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Heidesheim, Germany in June, 2012.

Asexual reproduction of the new Mandevilla plant by cuttings in a controlled greenhouse environment in Heidesheim, Germany, since June, 2012 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Inmanredgran’. These characteristics in combination distinguish ‘Inmanredgran’ as a new and distinct Mandevilla plant:

-   -   1. Upright and vining plant habit.     -   2. Strong and moderately vigorous growth habit.     -   3. Freely branching habit.     -   4. Glossy dark green-colored leaves.     -   5. Freely flowering habit.     -   6. Large red-colored flowers that resist fading.

Plants of the new Mandevilla can be compared to plants of the female parent selection. Plants of the new Mandevilla differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla are not as freely branching as         plants of the female parent selection.     -   2. Plants of the new Mandevilla have smaller leaves than plants         of the female parent selection.     -   3. Plants of the new Mandevilla have larger flowers than plants         of the female parent selection.

Plants of the new Mandevilla can be compared to plants of the male parent selection. Plants of the new Mandevilla differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla have larger and lighter         green-colored leaves than plants of the male parent selection.     -   2. Plants of the new Mandevilla flower earlier than plants of         the male parent selection.     -   3. Plants of the new Mandevilla have larger flowers than plants         of the male parent selection.

Plants of the new Mandevilla can also be compared to plants of Mandevilla hybrida ‘Lanlouisiana’, disclosed in U.S. Plant Pat. No. 25,873. In side-by-side comparisons plants of the new Mandevilla differ primarily from plants ‘Lanlouisiana’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are more freely branching than         plants of ‘Lanlouisiana’.     -   2. Plants of the new Mandevilla have smaller leaves than plants         of ‘Lanlouisiana’.     -   3. Flowers of plants of the new Mandevilla are more open and         larger than flowers of plants of ‘Lanlouisiana’.

Plants of the new Mandevilla can also be compared to plants of Mandevilla sanderi ‘Rio Red’, not patented. In side-by-side comparisons plants of the new Mandevilla differ primarily from plants ‘Rio Red’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are larger and stronger than         plants of ‘Rio Red’.     -   2. Plants of the new Mandevilla have larger leaves than plants         of ‘Rio Red’.     -   3. Plants of the new Mandevilla have larger flowers than plants         of ‘Rio Red’.     -   4. Flower color of plants of the new Mandevilla does not fade         whereas flower color of plants of ‘Rio Red’ fades.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring and early summer in 9.5-cm containers in a polyethylene-covered greenhouse in Almeria, Spain and under cultural practices typical of Mandevilla commercial production. During the production of the plants, day temperatures ranged from 20° C. to 35° C. and night temperatures ranged from 20° C. to 25° C. Plants were 15 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
